Aside from Harry's children, their friends at Hogwarts could also be main characters. For instance, a new character who comes from a different wizarding family but has a special connection with Harry's kids. Maybe they team up to solve a mystery in the school, like a hidden chamber or a strange magical phenomenon.
Harry and Ginny could also be important characters in the fanfic, even if not the main focus. They would be the parents, guiding and supporting their children. Their wisdom and experiences from their own adventures would play a role in how they raise their kids and how the kids face their own challenges. So in a way, they are part of the fabric of the story, influencing the main characters - their children.
The fanfic might focus on the relationships between Harry's future children. For example, they could have sibling rivalries or strong bonds of friendship. They might also have different personalities - one could be really outgoing and brave like Harry, while another could be more shy and studious. And they would all be growing up in a world that's still recovering from the war, so that could add a lot of depth to their stories.
The main characters in 'children of the future fanfic' could be children from different social backgrounds. For instance, there might be a poor orphan who discovers he has the ability to control time, and a rich kid who uses his family's advanced technology to help the group. There could also be a young scientist - in - training who is trying to figure out the secrets of the future world and is leading the other children in their adventures.
There's a good chance that his friends like Ron and Hermione would also be main characters. They were always by his side in the original series and would probably play important roles in this fanfic as well, perhaps helping Harry explore and understand his new - found aspects of his magic.
Maybe a group of friends who form a gaming team. Each friend has a different specialty in the game, like one is great at combat, another at strategy, and one at finding hidden treasures. They work together to achieve victory in the game world.
One option for the main character could be the child of Jake Sully and Neytiri. This character would inherit the unique skills and knowledge of their parents and face new challenges in the ever - evolving world of Pandora.
Maybe a group of rebels who are tired of the two existing power structures in their world. They could band together and through their combined efforts and different perspectives, find the third path to the future. Each of them could bring something unique to the table, like one being good at technology, another at persuasion, and so on.
Definitely the children of the original main characters. Serena's daughter would be a likely candidate. She'd inherit her mother's beauty and charm, but also her tendency for getting into trouble. And Blair's son, who'd be smart and ambitious, just like his mother, and would be vying for power in the Upper East Side social scene.
It could be Hermione, if it's related to the Harry Potter universe. She is extremely brainy and would fit the description well. There might also be other new female characters who are introduced specifically in this fanfic to add more depth to the story.
The main characters could also be a combination of students with different abilities or skills. In a world where they need to react to the future, someone with technological know - how, another with physical strength, and a third with great strategic thinking could all play important roles in how the 78th class as a whole responds.
A young Jedi apprentice who is curious about the future and goes on a quest to discover what lies ahead could be a main character. Also, an old, wise Sith lord who has lived through many eras and has a unique perspective on the future.
